Anyone know where to find an aftermarket battery for a Siemens TEK/Rexton BLU RCU remote? I’d like to keep a charged spare on hand, but I cannot find a part number on the original battery. It’s marked “Siemens Li-Ion Battery Rated 3.7V 1000mAh3.7Wh” (plus all the usual warnings, a manufacture date, and a serial number).

I’m guessing it could be the same as some common cell-phone battery.

That size battery seems to also be used by Ipod and LG phones. What kind of connector is it, a wire like this or built into the battery?

The battery has three contact pins set into the lower left end – looking down on it when it is installed. No dangling wired connector.

Perhaps if I take it to BatteriesPlus, they will recognize it – although I am sure I will not like their price.

my Tek that came with my Rextons over 3 years ago will still hold a charge all day on standby without any problem. If I’m streaming TV I just plug it in and lay it on the arm of the chair. Have you tried Costco? if I’m in the car all day I just it into one of the lighter outlets.

It’s been a long time, but I did get round to asking at Costco: battery has to be ordered and costs $22.99 – much cheaper than the $50 I found on line. Still haven’t decided whether to buy one.
